通讯录管理系统

功能:

完整的通讯录管理系统,了能够实现:添加联系人,显示联系人,删除联系人,查找联系人,修改联系人,清空联系人,退出通讯录等操作.全面的运用了C++基础知识.

// 封装函数显示该界面  如 void showMenu()
// 在main函数中调用封装好的函数
#include <iostream>
using namespace std;
#include <string>
#define MAX 1000

//设计联系人的结构体
struct Person
{
	string m_Name;//姓名
	int m_Sex;//性别 1.男 2.女
	int m_Age;//年龄
	string m_Phone;//电话号
	string m_Addr;//住址
};

struct Addressbooks
{
	//通讯录中保存的联系人数组
	struct Person personArray[MAX];

	//通讯录中当前记录联系人个数
	int m_Size;
};

//1.添加联系人
void addPerson(Addressbooks*abs)
{
	//判断通讯录是否已满,如果满了就不再添加
	if (abs->m_Size == MAX)
	{
		cout << "通讯录已满,无法添加!" << endl;
		return;
	}
	else
	{
		//添加具体联系人

		//姓名
		string name;
		cout << "请输入姓名: " << endl;
		cin >> name;
		abs->personArray[abs->m_Size].m_Name = name;
		//性别
		cout << "请输入性别: " << endl;
		cout << "1 --- 男" << endl;
		cout << "2 --- 女" << endl;
		int sex = 0;

		while (true)
		{
			//如果输入的是1或者2可以退出循环,因为输入的是正确值
			//如果输入有误,重新输入
			cin >> sex;
			if (sex == 1 || sex == 2)
			{
				abs->personArray[abs->m_Size].m_Sex = sex;
				break;
			}
			cout << "输入有误,请重新输入" << endl;
		}
		
		//年龄
		cout << "请输入年龄: " << endl;
		int age = 0;
		cin >> age;
		abs->personArray[abs->m_Size].m_Age = age;

		//电话
		cout << "请输入联系电话: " << endl;
		string phone;
		cin >> phone;
		abs->personArray[abs->m_Size].m_Phone = phone;

		//住址
		cout << "请输入家庭住址: " << endl;
		string address;
		cin >> address;
		abs->personArray[abs->m_Size].m_Addr = address;

		//更新通讯录人数
		abs->m_Size++;

		cout << "添加成功" << endl;

		system("pause");//请按任意键继续
		system("cls");//清屏操作
	}
}

//2.显示所有的联系人
void showPerson(Addressbooks* abs)
{
	//判断通讯录中人数是否为0,如果为0,提示记录为空
	//如果不为0,显示记录的联系人信息
	if (abs->m_Size == 0)
	{
		cout << "当前的记录为空" << endl;
	}
	else
	{
		for (int i = 0; i < abs->m_Size; i++)
		{
			cout << "姓名:  " << abs->personArray[i].m_Name << "	";
			cout << "性别:  " << (abs->personArray[i].m_Sex == 1 ? "男":"女")<< "	";
			cout << "年龄: " << abs->personArray[i].m_Age << "	";
			cout << "电话:  " << abs->personArray[i].m_Phone << "	";
			cout << "住址: " << abs->personArray[i].m_Addr << endl;
		}
	}

	system("pause");//按任意键继续
	system("cls");//清屏
}

//检测联系人是否存在,如果存在,返回联系人所在数组中的具体位置,不存在返回-1
//参数1 通讯录 参数2 对比姓名
int isExist(Addressbooks*abs,string name)
{
	for (int i = 0; i < abs->m_Size;i++)
	{
		//找到用户输入的姓名了
		if (abs->personArray[i].m_Name == name)
		{
			return i;//找到了,返回这个人在数组中的下标编号
		}
	}
	return -1;//如果遍历结束都没有找到,返回-1
}

//3.删除指定联系人
void deletePerson(Addressbooks*abs)
{
	cout << "请输入您要删除的联系人" << endl;

	string name;
	cin >> name;

	//ret = -1 没有查到
	//ret != -1;查到了
	int ret = isExist(abs, name);

	if (ret != -1)
	{
		//查找到人,要进行删除操作
		for (int i = ret; i < abs->m_Size; i++)
		{
			//数据迁移
			abs->personArray[i] = abs->personArray[i + 1];
		}
		abs->m_Size--;//更新通讯录中的人员数
		cout << "删除成功" << endl;
	}
	else
	{
		cout << "查无此人" << endl;
	}
	system("pause");
	system("cls");
}

//4.查找指定联系人信息
void findPerson(Addressbooks* abs)
{
	cout << "请输入您要查找的联系人" << endl;
	string name;
	cin >> name;

	//判断指定的联系人是否存在在通讯录中
	int ret = isExist(abs, name);

	if (ret != -1)//找到联系人
	{

		cout << "性别: " << (abs->personArray[ret].m_Sex == 1 ? "男" : "女") << "	";
		cout << "年龄: " << abs->personArray[ret].m_Age << "	";
		cout << "电话: " << abs->personArray[ret].m_Phone << "	";
		cout << "住址: " << abs->personArray[ret].m_Addr << endl;
	}
	else//未找到联系人
	{
		cout << "查无此人" << endl;
	}
	//按任意键后,清屏
	system("pause");
	system("cls");

}

//5.修改指定的联系人信息
void modifyPerson(Addressbooks* abs)
{
	cout << "请输入您要修改的联系人" << endl;
	string name;
	cin >> name;

	int ret = isExist(abs, name);

			if (sex == 1 || sex == 2)
			{
				//输入正确退出循环
				abs->personArray[ret].m_Sex = sex;
				break;
			}

		}
		
		//年龄
		cout << "请输入年龄: " << endl;
		int age = 0;
		cin >> age;
		abs->personArray[ret].m_Age = age;
		
		//电话

		string address;
		cin >> address;
		abs->personArray[ret].m_Addr = address;

		cout << "修改成功!" << endl;
	}
	else//未找到联系人
	{
		cout << "查无此人" << endl;
	}
	//按任意键后清屏
	system("pause");
	system("cls");
}

//6.清空联系人
void cleanPerson(Addressbooks* abs)
{
	cout << "是否确认清空?" << endl;

	cout << "2----不清空" << endl;
	int ret = 0;

	if (ret == 1 || ret == 2)
	{

		cout << "通讯录已清空!" << endl;
	}
	else

	}
